The 6RJ13 is a low burden hand reset high speed tripping relay suitable for applications where immunity to capacitance discharge & high minimum operation currents is not required.
The high speed relay coil is automatically protected from thermal damage by a series cutthroat contact once the relay contacts have picked up & latched.
The contacts & trip flag indication operate on application of a control voltage. The contacts & flag are reset using the front panel push button.
